CLOSE YOUR EYES just turned a nearly 50-year-old Korean jazz-funk deep cut into their boldest comeback yet. Their fourth mini album 256th Note dropped September 30, built around a title track that bridges two very different decades of Korean music.
Key Takeaways
- CLOSE YOUR EYES (클로즈유어아이즈) released their fourth mini album 256th Note and the title track “Drop That!” music video on September 30, 2026.
- “Drop That!” samples Yoon Si-nae’s 1979 song “이 밤을 즐겁게” and reworks it with 1990s street hip-hop production.
- The seven-track album includes “Baby Bossa Nova” featuring R&B artist Joo Hyelin and “Open Your Eyes” with pianist Yohan Kim and saxophonist Jacob Scesney.
- The group’s debut album ETERNALT sold about 316,000 copies in its first week, and third mini album blackout passed 570,000.
CLOSE YOUR EYES Release 256th Note
CLOSE YOUR EYES dropped their fourth mini album 256th Note on September 30, 2026, along with the music video for title track “Drop That!” The release follows the group’s April 2025 debut and marks their third comeback within roughly a year and a half. 256th Note contains seven tracks, matching the format of the group’s previous mini albums.
The press showcase for the album took place at The Riverside Hotel in Seocho-gu, Seoul. All seven members attended: Jeon Min-wook, Ma Jingxiang, Jang Yeo-jun, Kim Sung-min, Song Seung-ho, Kenshin, and Seo Kyoung-bae.
Why “Drop That!” Connects Two Eras
“Drop That!” samples Yoon Si-nae’s 1979 jazz-funk song “이 밤을 즐겁게.” The production team reinterprets the sample through a 1990s street hip-hop style. This pairs a nearly 50-year-old Korean recording with a production approach rooted in a different decade entirely.
The result places two distinct eras of music inside one title track. Listeners get a direct link to 1970s Korean jazz-funk, filtered through hip-hop techniques associated with the 1990s.
256th Note Tracklist and Credits
The seven songs on 256th Note cover several different production styles, from experimental piano work to bossa nova. Pre-release track “Open Your Eyes” features pianist Yohan Kim and saxophonist Jacob Scesney over an experimental piano arpeggio paired with fast drums. All seven members took part in writing closing track “Eternity.”

The Brazilian Link in “Baby Bossa Nova”
“Baby Bossa Nova” draws on Brazilian bossa nova and features R&B artist Joo Hyelin. For listeners in Brazil, Argentina, Chile, Mexico, Peru, and Colombia, the track offers a direct musical reference point inside a Korean comeback. Streaming already makes up a large share of how these regions consume K-pop, and this track gives that audience a genre they can recognize immediately.
Global Release Times
256th Note went up at 6 p.m. KST on September 30. That timing lands at different hours across the group’s international fan base.

The Sales Benchmark This Comeback Must Follow
256th Note enters a sales track record built over three previous mini albums. ETERNALT, the group’s debut release, sold about 316,000 copies in its first week after the April 2025 launch. Third mini album blackout then passed that mark by a wide margin, recording more than 570,000 first-week sales.
Those three releases combined pushed the group’s cumulative sales to roughly 1.2 million copies. Hanteo, Circle, and Billboard have not yet published first-week figures for 256th Note.
